Audacity 99

99 Things to do with Audacity.

Perhaps 99 is a bit hopeful but ......

1. Speed of sound in air
2. Speed of sound through a lab table
3. Speed of sound through jelly (I will do it one day, honest)
4. Measuring time interval between bounces of a ball
5. Measuring speed of dropping magnet in a burette tube
6. rolling a spherical neomagnet down a ramp and measuring speed
7. Measuring speed of ball bearings fired by a Gaussian gun
8. time period of a pendulum (neomagnet on a string)
9. seismograph
10. speed and acceleration of a toy car down a guttering ramp
11. spherical neomagnet a roller coaster made of clear plastic tubing (speed, KE and GPE)
12. conservation of momentum with neos stuck to mechanics trolleys/air track carts
13. I've made a working wind turbine, which is just the coolest thing and generate AC (Vid below) JF

    something I picked up from my sixth form placement turning sine waves into square ones - is this useful?
15. A2 Coursework - one of the students hit a metal rod holding it in the middle, then recorded the sound with audacity. He then identified the harmonics. he then supported the rod in 2 places and repeated it to get further harmonics
